Castle Rock is a bluff of exposed St. Peter Sandstone from the Middle Ordovician period. Newly exposed sections are white quartz, while older areas have browner tints from the formation of limonite. The bluff is along the axis of the Sandwich Fault Zone, separating Ordovician exposures from those of the Cambrian period.
Castle Rock State Park was one of eleven state parks slated to close indefinitely on November 1, 2008 due to budget cuts by former Illinois governor Rod Blagojevich. After delay, which restored funding for some of the parks, a proposal to close seven state parks and a dozen state historic sites, including Castle Rock, went ahead on November 30, 2008. After the impeachment of Illinois Governor Blagojevich, new governor Pat Quinn reopened the closed state parks in February. In March 2009 Quinn announced he is committed to reopening the state historic sites by June 30, 2009.
